Interlaboratory Harmonization of Measuring Techniques for Multispectral SignatureMaterials

摘要

On the basis of existing measuring equipment, acquired over the years, threelaboratories from the defense research and industry in Sweden and Norway have made co-operative efforts to examine the possibility of harmonizing their measuring techniques. Since modern materials must fulfill specified quantitative physical requirements in widely different parts of the electromagnetic spectrum, it is essential that measurements taken by the laboratories concerned are of comparable accuracy, and that errors caused by different measuring techniques are eliminated in so far as they are of practical significance. First, a complete overview was prepared for the equipment and the measuring procedures used by the parties. Second, comparative measurements were carried out in order to establish the level of descrepancies involved. Third, these results served as guides for harmonization of the measuring techniques.
